Process for manufacturing to a tape with specific pattern interval

Abstract

In a process for manufacturing to a tape with specific pattern interval, there are utilized at least two kinds of ultraviolet-fluorescent yarns with different chromophore, which is spun out of dope kneaded with a fluorescent material. When ultraviolet-fluorescent yarns and colorless yarns are wound around a warp beam or drum with or without infrared-fluorescent yarns, the ultraviolet-fluorescent yarns are arranged repeatedly in specific color order in the traverse direction during the warping operation. In the process, these yarns as the warp are also woven into a double-wide textile with a wide loom.

What is claimed is: 
     
       1. A process for manufacturing a tape with specific pattern interval, the tape having at least two kinds of fluorescent yarns different from each other in chromophore, the fluorescent yarns being spun out of dope kneaded with a fluorescent material, the process comprising:
 arranging the fluorescent yarns in specific color order in transverse direction while winding the fluorescent yarns together with colorless yarns around a slasher beam; 
 rewinding the fluorescent and colorless yarns wound around the slasher beam to a warp beam during warping operation; 
 weaving the fluorescent and colorless yarns as the warp with a loom while the fluorescent yarns are interwoven in specific color order in the transverse direction, the specific color order being repeated in repetitive pattern over the total width of a double-wide textile; and 
 cutting the double-wide textile into tapes having widths by heat-cutting, the width of each tape thus obtained being at least twice the fundamental width of the repetitive pattern. 
 
     
     
       2. The process according to  claim 1 , wherein a prescribed width of a first row and an end row of the fluorescent yarns are defined while arranging the fluorescent yarns repeatedly in specific color order in the transverse direction. 
     
     
       3. The process according to  claim 1 , wherein infrared-fluorescent yarns are wound together with ultraviolet-fluorescent yarns and the colorless yarns around the warp beam by beam-warping, and all the fluorescent yarns and the colorless yarns are woven as the warp with a wide loom. 
     
     
       4. The process according to  claim 1 , wherein a double-wide satin textile on which a portion of the warp comes to a surface of the satin textile is woven while opening rows of the warp, and inserting colorless yarns of synthetic fiber as the woof into a shuttle path caused by the opening of the rows within a wide loom. 
     
     
       5. The process according to  claim 1 , wherein the warp and the woof composed of colorless yarns is made of a non-bleached polyester fiber.
